Application April 20,

1 Claim.

It is generally known that the old-fashioned springing or diving deviceconsisted of a plank of a suitable length, one end of which is fastenedor held firmly, while the opposite end thereof was suspended from adock, pier or the earth, forming thereby a Very amusing and suitablediving device. However this type was cumbersome and could not beresorted to unless a plank of this description was available at thewater when desired. This type of board is also more or less dangerous inthat the diver is liable to incur splinter wounds in the feet orotherwise in handling the board.

One of the objects of our invention is to overcome the difficultiesabove referred to.

Another object of our invention is that we have devised a neat andcompact device that may be readily transported in an automobile orotherwise to and from the beach, and which does not require dismantlingfor use or for packing purposes.

A further advantage of our invention is that it is light in weight,inexpensive to manufacture and accordingly may be placed upon the marketat a price well within the reach of everyone.

It will become apparent during the disclosure of the following detaileddescription that the inventon possesses further advantages, which arefurther illustrated throughout the accompanying drawing, and more fullypointed out in the subjoined claim.

With reference to the drawing:

Figure 1 is a side elevation of the complete invention, and Figure 2 isa rear elevation of the same.

Figure 3 is a front elevation of the invention.

Figure 4 is a perspective View of one of the spring clips employed.

Figure 5 is a greatly enlarged partial view of the invention takensubstantially upon the line 5-5 of Figure 1.

The invention comprises a top board indicated by the numeral I, andhaving the top surface and all edges thereof completely covered with asuitable cloth 2 for this purpose. The said cloth secured to the saidboard by means of suitable tacks 3, as indicated. Cloth 2 serves tofacilitate comfort for the bare feet in the use of the device.

1934, Serial N0. 721,463

One end of the board I is secured to elongated block II by the use ofhinges 5, as shown. The opposite end of the said board is adapted to besuspended uniformly upon spring 6, one end of the said springs securedtothe underneath surface of the board I by clips 'I respectively, andthe opposite end of the said springs bearing upon the top surface of andsecured to baseboard 8 by clips 'IA respectively. Clips 'I and 'IA areconnected to the respective boards I and 8 by nails 9 through holes I0in the said clips respectively.

Block 4 is rigidly secured to base board 8 by wood screws II whereindicated.

It is now very clearly understood that board I will effectivelyoscillate when subjected to human weight upon the outer end thereof andwhich will fully and completely accomplish the purpose for which it isintended.

By virtue of the particular construction and design of our inventionthroughout, the same is thereby rendered indestructible, and withordinary care the same should endure for an indefinite period of time,hence the advantage acquired from an economical viewpoint.

Having thus described our invention, what we claim as new is:

In a device of the class described, a wooden base board, a wooden blockextending transversely across the top face of the rear end of the baseboard for the full width thereof and being fixedly secured thereto, awooden top board of substantially the same size as the base board, therear end of the top board being hingedly connected to the top of theWooden block at the rear edge thereof, a pair of vertically arrangedcompression coil springs interposed between the forward end portions ofthe base and top board, clips secured to the inner opposed faces of therespective boards, each clip being formed at its forward end with anoffset loop for connection with the adjacent convolution of therespective springs, whereby lateral displacement of the coil springswill be prevented during the vertical swinging movement of the topboard.
